Acquisition Mode: 3D CT

X-ray Computed Tomography (CT) is a non-destructive imaging technique that combines a number of scans taken at various angles to produce cross-sectional images or ‘slice views’. The slice views are used to produce full 3D reconstructions of the core samples so that three-dimensional structures can be visualised without the need to remove the liner. CT reconstructions provide valuable quantitative data as well as visual information about core quality for sub-sampling or further analyses.

How can you benefit from 3D CT?

X-ray datasets, collected through full 3D-CT scanning, provides invaluable quantitative data and insight into the internal nature of core samples. 3D CT provides geoscientists with an image sequence of axial slices that can be processed into a data volume for 3D visualisation, or used within image processing software to look at spatial distribution of geological structure or stratigraphy. Through 3D data, geoscientists can better plan sampling/plugging points, or extract derived values such as density.

Orthogonal or unwrapped slabs generated from 3D CT will present crisper features within the core images, and so CT datasets provide better clarity of geological features such as bioturbation, laminae, vugs, gravels or pore space.

CT is the most flexible of the three data acquisition types offered by Geotek, and provides geoscientists with datasets that can be utilised for a wide variety of applications.

How does it work?

Currently Geotek offer two methods of CT data acquisition; Circular CT scans and Helical CT scans:

Data Acquisition Software

Geotek’s X-ray acquisition software was specifically developed for geoscience applications and has a friendly graphic user interface. The user may select the X-ray technique they wish to use for the scanning whilst setting up the scan at the start of a project.
